Should I choose water-based or oil-based die lubricant?

Mold release agent is mainly used to improve the mold release of die casting, protect the mold, regulate the temperature of the mold, mold release agent has high temperature resistance, scouring resistance, good lubrication and cooling effect.

A, water-based mold release agent: the main feature, that is, water as a diluent, its composition can be completely integrated with water, and then sprayed in the mold, to play the effect of mold release. There are water-based mold release agent, in line with national policies, environmental protection requirements, and low overall cost, directly diluted with water to use.

Water-based mold release agent advantages: the product after the processing of simple; disadvantages: the number of times the mold is less, the mold is easy to dirty, the release effect is not good enough relative to the oil-based.

Second, the oil-based mold release agent: its ingredients are oily substances, can not be fused with water, the use of diluent (methylene chloride, white electric oil, etc.). Oil-based release agent will produce residues on the product, affecting the secondary processing of the product, so most of the mold release agents used in the market now are water-based release agents.

Advantages of oil-based release agents: stronger mold release, not easy to dirty the mold, but the surface of the product is easy to dirty; disadvantages: less mold release times, the surface of the product is easy to blister and delamination, the latter part of the processing trouble.

Good quality mold release agent, also called release agent, its characteristics and role is its active ingredients, after spraying, quickly form a dense smooth, thin layer of film on the surface of the mold. This layer of film has a high temperature, impact, high pressure, cooling effect, effective organization of aluminum and mold adhesion, the coating gas emission is small, the die casting pores generated by less. Water-based mold release agent, in line with national policies, environmental protection requirements, and low overall cost, directly diluted with water to use.

Modified polyethylene / polypropylene wax emulsion can be used as die casting mold release agent, can shorten the release cycle, improve production efficiency; reduce the production process of waste; reduce energy consumption, the use of process more environmentally friendly, while extending the service life of the mold.
